Question

A cardboard box is 1.2 in long, 72 cm wide an54 cm high. How many bars of soap can be put into it if each bar measures $6cm\times 4.5cm\times 4cm$?

Answer 1

Length of carboard box (l)

=1.2 m=120 cm.

breadth (b)=72 cm.

Height (h)=54 cm.

$\therefore$ Volume of box $=l\times b\times h=120\times 72\times 54c{m}^3$

$=466560c{m}^3$ Volume of one soap bar $=6\times 4.5\times 4c{m}^3$

$=108c{m}^3$

$\therefore$ No.of bars to be kept in it $=\frac{466560}{108}$

=4320
